Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, device, and storage medium for reducing g.fast port crosstalk.
Background
With the development of High-bandwidth services such as ultra-High-definition network video, Virtual Reality (VR) technology, big data, cloud computing and the like, the requirement of a user on access bandwidth is higher and higher, and the traditional ADSL (Very High Speed Digital Subscriber Line), VDSLL (Asymmetric Digital Subscriber Line) and Vectoring technologies are far from meeting the requirement of the user on High bandwidth. G.fast has emerged, which allows users to reach the speed of the fiber on the original copper medium without having to redeploy the fiber. However, g.fast is forward compatible with VDSL technology, and in terms of spectrum usage, g.fast uses 106MHz/212MHz, occupies a frequency band below VDSL (30MHz), so that g.fast line and VDSL line have overlap in a frequency band below 30MHz, because crosstalk generated in the same frequency band is very large, stability of the line is poor, and internet experience of a user is reduced.
In order to solve the serious problems of unstable line, reduced rate, etc. caused by excessive crosstalk, the equipment operator usually adopts the configuration to close the sub-carrier channel (hereinafter referred to as TONE) with a small number of carrying bits in the VDSL frequency band in advance to reduce the crosstalk, but the configuration is limited to the existing VDSL CPE (subscriber end equipment of the ultra-high speed digital subscriber line) on the existing network. If a user accesses the VDSL CPE by himself without the knowledge of the operator, the g.fast port may generate a large amount of errors and may cause the port to drop if the user does not operate to turn off the interfered TONE in the VDSL band again. The speed of the g.fast port will also be reduced significantly if VDSL TONEs (sub-carriers) are not turned on when there is no VDSL CPE present in the existing network. This manual configuration would incur significant manual maintenance costs for the operator.
The prior art is therefore still subject to improvements and enhancements.

Referring to fig. 1, the method for reducing g.fast port crosstalk according to the present invention includes the following steps:
s100, obtaining a link establishment state of an ultra-wideband copper wire access technology G.FAST port, wherein the link establishment state comprises success and failure.
In this embodiment, the g.fast port is a user port of a communication device supporting ITU-t g.9700/g.9701 standard, the link establishment mode of the port is g.fast mode, if the link establishment state of the g.fast port is failed, it indicates that the port is interfered by the VDSL band, at this time, in order to improve the stability of the line, it is necessary to close an interfered subcarrier channel (hereinafter referred to as TONE) in the VDSL band, and if the link establishment state is successful, it is necessary to further determine whether to close the TONE in the VDSL band to reduce crosstalk, generally, an overlapping band of the g.fast line and the VDSL line is 2.2MHz to 30 MHz. The specific steps of step S100 are shown in fig. 2.
Please refer to fig. 2, which is a flowchart of the step S100, including the following steps:
s101, reading an online state marking bit of an ultra-wideband copper wire access technology G.FAST port, wherein the online state marking bit comprises 1 and 0;
s102, the g.fast port with the presence flag bit of 1 is used as the g.fast port with successful link establishment, and the g.fast port with the flag bit of 0 is used as the g.fast port with failed link establishment.
In this embodiment, in order to facilitate reading of the link establishment state of the g.fast port by a device that reduces crosstalk of the g.fast port, the link establishment state is represented by a flag bit, and first, an online state flag bit of the g.fast port is read, and if the online state flag bit is 1 (port _ online ═ 1), it is determined that the link establishment state of the g.fast port is successful; if the presence flag bit is 0(port _ online ═ 0), it is determined that the link establishment status of the g.fast port is failure.
Preferably, when determining that the link establishment status of the g.fast port is failed, all subcarrier channels of the g.fast port whose link establishment failed in the VDSL band are closed, in other words, if the link establishment status of the g.fast port is failed, it indicates that the g.fast port may be interfered by the VDSL band, and at this time, to avoid crosstalk, and to ensure stability of the line, it is necessary to close the TONE in the VDSL band.
And S200, acquiring the bit distribution condition of each G.FAST port successfully establishing the link in a polling mode.
In this embodiment, the polling time may be set according to an actual situation, for example, set to any time point within 10 minutes to 6 hours, where the bit distribution of the g.fast port is a bit ratio carried by each subcarrier channel under the g.fast port, and as the lower the number of bits carried by a subcarrier channel is, the greater the crosstalk generated by the subcarrier channel is, the present invention determines whether to close the subcarrier channel by determining the number of bits carried by the subcarrier channel, so as to achieve the purpose of reducing the crosstalk and ensuring the line stability.
Preferably, each g.fast port includes 2048 subcarrier channels, each subcarrier channel has a spacing of 51.75KHz, and each subcarrier channel has a carrying upper limit, which is 12 bits.
And S300, judging whether the bit number borne by each subcarrier channel of the G.FAST port successfully establishing the link under the VDSL frequency band reaches a preset standard or not in a polling mode according to the bit distribution condition.
In this embodiment, the polling time may be set according to an actual situation, for example, set to any time point within 10 minutes to 6 hours, and the preset standard may be determined according to an actual communication situation, so that a preset standard, that is, a bit number threshold, needs to be set before the determination, and when the bit number threshold is reached, it is indicated that the standard is reached, otherwise, it is determined that the standard is not reached. A detailed flowchart of step S300 is shown in fig. 3.
Please refer to fig. 3, which is a flowchart of the step S300, including the following steps:
s301, multiplying the bit ratio carried by each subcarrier channel by the total bit number of the current G.FAST port, and counting the bit number carried by each subcarrier channel of the G.FAST port with successful link establishment under the VDSL frequency band;
s302, whether the bit number carried by each subcarrier channel is larger than or equal to a preset bit number threshold value or not is judged in a polling mode, if yes, the subcarrier channel is judged to reach the standard, and if not, the subcarrier channel is judged not to reach the standard.
Specifically, the obtained bit ratio carried by the subcarrier channel is multiplied by the total bit number of the current G.FAST port, namely, the bit number carried by the subcarrier channel is obtained, and then the bit number is compared with a preset bit number threshold value, it can be determined whether the signal reaches the standard, preferably, the bit number threshold is 5, and after the test, the stability and link establishment rate of the g.fast line port are lower, and of course, in other communication environments, the bit number threshold may also be other values, which is not limited in the present invention, and if the bit number carried by the subcarrier channel is greater than or equal to 5, judging that the bit number carried by the sub-carrier channel reaches the standard (if the bit number carried by the sub-carrier channel reaches the standard, the TONE crosstalk is small and the stability of the line is not influenced), otherwise, judging that the bit number carried by the sub-carrier channel does not reach the standard (if the bit number carried by the sub-carrier channel does not reach the standard, the TONE crosstalk is large).
And S400, opening the subcarrier channel with the qualified bit number, and triggering the operation of closing the subcarrier channel with the unqualified bit number when the G.FAST port is disconnected.
Specifically, for the subcarrier channel with the standard bit number, the crosstalk is small, so the invention opens the subcarrier channel to improve the link establishment speed of the G.FAST port; for the subcarrier channel with the unqualified bit number, the generated crosstalk is large, because the G.FAST port to which the subcarrier channel belongs is still in the successful state of the link establishment, the G.FAST port is not immediately closed in order to not influence the normal use of a user, the subcarrier channel with the unqualified bit number is triggered to be closed when the G.FAST port is disconnected.
The invention judges whether the crosstalk of the TONE is larger or smaller by acquiring the bit number carried by the TONE under the VDSL frequency band of the G.FAST port and corresponding calculation, if larger, the TONE is closed, and if smaller, the TONE is opened. The method for closing and opening the TONE can improve the stability of the line, simultaneously improve the internet surfing experience and the satisfaction degree of a user, automatically open the TONE under the condition of small crosstalk and improve the link establishment speed of the line. The method can reduce the manual maintenance workload of the operator and increase the effective workload of the operator.
